Product details

Single-cell Li-ion fuel gauge with Impedance Track

The Texas Instruments BQ27510DRZR-G3 is a single-cell Lithium Ion battery monitor that uses the Impedance Track™ algorithm to report state-of-charge with better accuracy than voltage-based gauges, especially under varying load and temperature. Communication with the host microcontroller runs over an I²C interface, making it a straightforward addition to existing battery-management buses.

Industrial temperature grade and active production

It remains a current-production choice for new designs.

Package and mounting for production

The 2.5x4 mm body suits space-constrained battery packs. Cut Tape works for prototyping and low-volume runs.

Frequently asked questions

How does BQ27510DRZR-G3 measure battery capacity?

It uses the Impedance Track algorithm, which measures the battery's internal impedance along with voltage and current to compute state-of-charge. This method compensates for load variation and temperature drift, giving a more reliable fuel-gauge reading than simple voltage lookup.

Is BQ27510DRZR-G3 compatible with 2-cell batteries?

No. The part is designed for single-cell Lithium Ion packs only. A 2-cell stack would exceed the input range of the monitor.

What is the I²C address of BQ27510DRZR-G3?

The I²C address is set internally and is documented in the device datasheet. It is a fixed address — no external address pins are provided on this package.
